Nanotechnology in Agri-Food Production: A Comprehensive Review of Innovations, Applications, and Future Perspectives

Abstract

Nanotechnology has emerged as a transformative force in the agri-food sector, offering innovative solutions to address the interconnected challenges of food security, sustainability, and environmental protection. This review provides a comprehensive analysis of nanotechnology applications across the entire agri-food production continuum—from pre-harvest crop management to post-harvest processing and packaging. We examine the role of nano fertilizers and nano pesticides in enhancing nutrient use efficiency and reducing chemical inputs, with studies demonstrating crop yield improvements of up to 30% and pesticide reduction of 40%. The review explores nano sensing technologies for real-time soil and plant health monitoring, smart delivery systems for targeted agrochemical release, and advanced nanocomposite packaging materials that extend shelf life while enabling real-time food quality monitoring. We critically assess the environmental and safety considerations associated with nanoparticle application, including impacts on soil microbiomes, potential for bioaccumulation, and the current regulatory landscape. Finally, we identify knowledge gaps and propose future research directions to facilitate the responsible integration of nanotechnology into sustainable agri-food systems.
